From an existing house to a suitable extension
For an extension or additional storey in Flevoland, it helps to compare the original house drawings with what was actually built. Repeated house designs within a development do not automatically mean that later alterations are identical. Municipal figures provide context for the housing profile; the structural engineer then assesses the load paths, connections and foundations of your own building. Describe which parts will remain and which will be added.

| Map code | Dutch soil classification: first unit | Area (ha) | Share of mapped area |
|---|---|---|---|
| Mn35Av | Kalkrijke poldervaaggronden; lichte klei, profielverloop 5 | 19,230 | 15.3% |
| Mn35A | Kalkrijke poldervaaggronden; lichte klei, profielverloop 5 | 16,314 | 13.0% |
| Mn25Av | Kalkrijke poldervaaggronden; zware zavel, profielverloop 5 | 8,365 | 6.7% |
| Mn35Ap | Kalkrijke poldervaaggronden; lichte klei, profielverloop 5 | 7,691 | 6.1% |
| Mn25A | Kalkrijke poldervaaggronden; zware zavel, profielverloop 5 | 6,554 | 5.2% |
| Other units | Other mapped soil polygons | 67,374 | 53.7% |
The shares are calculated within the soil polygons on the map, not across all land or all building addresses. For compound map codes, the name of the first unit is shown. The map describes shallow soil; built-up areas are not fully mapped. It does not establish bearing capacity or determine whether piles, pad footings or strip foundations should be used.

How much renovation takes place?
The CBS tables used here do not provide a complete local renovation count for Flevoland. We therefore do not estimate this from population, new homes or a national percentage. These sources also do not establish which type of renovation is most common.
